Research Interests

My overarching research goal is to understand the contemporary (ecological) and historical (evolutionary) processes responsible for observed patterns of ecological community structure. My research program is broadly focused on stream fish assemblages of temperate North America and neotropical Central America. These systems are fantastic for examining and quantifying species interactions, and this is partially due to the great species richness that is often observed even in short stretches of stream (i.e., high potential for species interactions!). Using these systems, I examine biotic and abiotic factors that influence distributions of fishes across space and through time.

In short, I integrate species occurrence/abundance, habitat use, phylogenetics, morphology, and spatial scale to understand how and why fishes are distributed within and among communities.

Courses taught (UCM): Ichthyology, Freshwater biology, Limnology, Biogeography, Marine biology, Research grant writing, Environmental science
